This war resulted from issues that were not completely resolved from Cresian War I. The war ended with Avanan defeat, leading to the independence of the fifteen states from the Republic of Cresia.

Avana refers to the war as the Second Cresian Civil War, the other northern provinces refer to the war as the Cresian War of Revolution, while the southern provinces call it the Second Cresian War of Revolution.
